The American comic Mad magazine began in 1952. The TV and movie parodies were popular, but while the US edition never covered Space: 1999, the UK edition did. The parodies were imitated by several competitors, notably Cracked magazine (from 1958) and Marvel's Crazy magazine (from 1973).
Space: 1999 Comic Anthology by Shaqui Le Vesconte (2023) discusses the parody comic strips p184-195.
